Section 3 - INSTALLATION
Connect the extension cable tightly to the accelerometer and safety wire the
connector. A major cause of nuisance alarms is a loose connection to the
accelerometer. Route the extension cable away from the turbine, and in the case
of steam injection turbines, away from any steam manifolds. Secure the
extension cable at frequent intervals to prevent excessive vibration. Cable
vibration can induce charge on the conductors which appear as noise to the
input of the charge amplifier.
CAUTION
To prevent interference of machinery monitoring, radio
transmitters should not be operated/used within 6 feet
(2 metres) of the accelerometer interface module.
